 TECHNICAL NOTES

The Philippine Statistics Authority (PSA) conducted the 2020 Census of Population and Housing (CPH) in September 2020. The 2020 CPH was a nationwide government undertaking that involved the collection, compilation, evaluation, analysis, publication, and dissemination of data on population, housing characteristics, household characteristics, and barangay characteristics in each barangay, city/municipality, province, and region in the country. With reference to the first census in 1903, the 2020 CPH was the 15^th census of population and the 7^th census of housing in the Philippines.

The census of population is the source of data on the size, distribution, and composition of the population. The census of housing, on the other hand, provides information on the supply of housing units and other information on the structural characteristics and facilities that have bearing upon the maintenance of privacy and health and the development of normal family living conditions. These data were collected for different geographic units, that is, from the national down to the barangay level. These information are vital in making rational plans and programs towards national and local development.

Definition of Census Terms and Concepts

A household is a social unit consisting of a person living alone or a group of persons who sleep in the same housing unit and have a common arrangement in the preparation and consumption of food.

In most cases, a household consists of persons who are related by kinship ties, such as parents and their children. In other instances, however, several generations of familial ties are represented in one household while, still in other cases, even more distant relatives are included as members of the household.

Some household members may have no relationship to the head of the household, for example helpers, boarders, and nonrelatives. They are considered as members of the household provided that they sleep in the same housing unit and have a common arrangement for the preparation and consumption of food with the household and that they do not go home to their family at least once a week.

A group of unrelated individuals, as in the case of a group of students or workers who decide to rent a place and make common arrangements for the preparation and consumption of their food, constitutes one household.

Usually, a household is an entire group of persons who customarily live in the same housing unit. However, there are cases when two or more distinct family groups or groups of unrelated persons maintain separate food arrangements even though they share one housing unit. Each of these two or more distinct groups constitutes a household.

A person who shares a housing unit with a household but separately cooks his/her meals or consumes his/her food elsewhere is not considered a member of that household. This person should be listed as a separate (one member) household.

In determining household membership, the basic criterion is the usual place of residence or the place where the person usually resides. This may be the same or different from the place he/she is found at the time of the census. As a rule, it is the place where he/she usually sleeps.

Household population comprises of persons who belong to a household.

Institutional Living Quarter (ILQ) is a structurally separate and independent place of abode intended for habitation by large groups of individuals. Such a quarter usually has certain common facilities such as a kitchen and dining room, toilet and bath, and lounging area which are shared by the occupants.

Institutional population comprises of persons who are found living in ILQs. They may have their own families or households elsewhere but at the time of the census, they are committed or confined in ILQ, wherein they are usually subject to a common authority or management or bound by either a common public objective or a common personal interest.
